Abstract
샤프펜슬은 본체, 본체 후방부에 회전가능하고 탈착가능하게 장착된 캡, 그리고 본체에 내장된 심 진행기구를 지닌다. 캡의 회전은 심 진행기구를 작동시켜 연필심을 전진시킨다. 그 샤프펜슬은 연필심의 파손을 방지하고 제조원가도 낮다. 회전캠 기구는 연필심을 진행시키는 심 진행기구 후방에 위치한다. 회전 캠 기구는 캡이 회전에 따라 회전하는 캠과, 회전캠에 맞물리도록 편향된 캠 슬리브를 지닌다. 캠 슬리브 전방부의 내경이 심 진행기구 후방부의 외경보다 커서 심 진행기구 후방부가 측방향 간극을 유지하면서 캠 슬리브 전방부에 삽입된다. 심 진행기구 후방부의 내경이 연필심 외경보다 커서 역시 그곳에 간극이 형성된다.The mechanical pencil has a main body, a cap rotatably and detachably mounted to the rear of the main body, and a shim mechanism embedded in the main body. Rotation of the cap activates the shim advancement mechanism to advance the pencil lead. The mechanical pencil prevents breakage of the pencil lead and has low manufacturing cost. The rotary cam mechanism is located behind the shim progression mechanism for advancing the pencil lead. The rotary cam mechanism has a cam that the cap rotates with rotation and a cam sleeve biased to engage the rotary cam. The inner diameter of the cam sleeve front portion is larger than the outer diameter of the rear portion of the shim progression mechanism so that the rear portion of the shim progression mechanism is inserted into the cam sleeve front portion while maintaining the lateral gap. The inner diameter of the rear part of the shim progression mechanism is larger than the outer diameter of the pencil core so that a gap is formed there.
이러한 간극들은 연필을 떨어뜨렸을때도 심 진행기구의 비틀림으로 인하여 연필심이 부러지는 것을 방지한다.These gaps prevent the pencil lead from breaking due to the twisting of the shim mechanism even when the pencil is dropped.
